CONDUCTOR SUPPORT.

. citizen of the United States of America, re-

ber 1' provided with a threaded recess to re tit) siding at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Conductor Supports, of which the following is a specification.

My invention. relates to a device for supportin r electric conductorsand has particu lar re erence to a dew'oe for suspending a trolley wire from its overhead support.

The object of my invention is to produce a device which is simple,.easy of construction and simple in its installation or reinoval.

My invention resides in the novel construction, combination and relation of the various parts as hereinafter more fully described and set-forth.

In the drawing accompanying this spec-ification Figure 1 is a side View in elevation of my invention shown as attached to a trolley Wire and with a portion broken away to show to better advantage the interior construction.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a top view of Fig. 1. Fig. 41 is -a sectional view on the line 1-4 of Fig. 1.

Fig. 5 is a sectional view of Fig. 1 on the line 5-5 and also shows the relation of my invention to the overhead support H from which the trolley wire is suspended.

Fig. 6 is a sectional view taken the same ready to receive a trolley wire. In'my preferred construction embodying my nvention Iemploy a supporting memceive a threaded stud of the overhead support or' hanger. The lower end ofv thesupporting meinber 1 is provided with a horizonta-l pintle 2- secured to the supporting member 1 by means of the neck 3. ,The outer surface of the member 1 is provided with threads on which is mounted the internally threaded nut' i provided with the faces for the application of a wrench used in installing my invention upon the trolley wirep p j Engaging and suspended by the pintle 2 is a pair of clamping jaws 66 provided at their upper end with an arcuate hook 7 for,

the purpose of engaging with and suspending the jaws from the pint-le. The arcuate member 7 does not entirely surround half the circumference of the pintle 2, but leaves a perceptible space 8 between the upper portions of the members 77 to permit the jaws to pivot upon the pintle 3 in the operation of spreading the j awsto receive the trolley wire 9. The lower end of the jaws 66 are each provided with a ridge 10 adapted to engage the groove in the trolley wire 9.

To assist in maintaining the jaws 6 in position upon the pintle and to move the jaws into engagement with the trolley wire I employ a casing 11 of elongated formationadapted to slip over the member 1 and engage the shoulder 12 on each jaw. The member 11 is provided with a lip 13 extending substantially the full length thereof to engage the shoulders 1212. This engagethroughout the length of the jaw.

In order to assemble my invention the casf ing 11 is provided with slots 14 which open into the central recess 15 to allow the pintle 2 and neck 3 to be inserted within the casing.

As the casing is open throughout its upper face due to the slots 141 and re cess 15 I taper the upper surface of the casing where it engages with the surface of the nut 1 inorder that any pressure brought upon the casing by the nut- 4 will tend to.

prevent the casing from spreading. The inner face 16 of the lips 13 are so spaced as to prevent the upper portion of the jaws from spreading to any appreciable extent thereby maintaining them in pivotal engage-merit with the pintle.

To assemble my invention I first insert the pintle portion of the supporting member through the slot 14 and allow the supporting-member to drop to its lowest po-v sition in which case the pintle willproject a sufficient distance below the lips 13 to permit the positioning of the jaws 6 upon the pintle. The jaws 6 are then heldin position upon the pintle and the casing11 allowed to take a position in which the lips 13 engage the shoulder 12 and the nut 4: is then rotated into position either in engagement with the casing 11 or approximately so. The parts are then put in. an assembled assemble them unless the nut 4 is removed lwith the trolley wire.

a suflicient distance away from the casing 11. To install my invention upon a trolley wire and hanger the nut i is first moved outward upon the member 1 by rotation which permits freedom of movement between the nut t and the casing 11. The casing 11 is then moved slightly away from the aws thus permitting the j aws to pivot about the pintle 2 and the lower end to open up suiiiciently to receive the trolley wire. Before inserting the trolley wire between the portion 1010 of the jaws the support as a whole is attached to the overhead hanger H by rotating the whole device and screwing the member 1 upon the stud S-until the face of the member 1 engages with the face of the support H. If the jaws are not then in alinement with the trolley wire the device is backed off a sufficient amount to aline the jaws with the trolley wire. The trolley wire is then inserted between the jaws and the nut 4: moved into engagement with the casing-l1 by rotating the nut. .Further rotation of thelnut will force the casing 11 downward andthe lips 13 into stronger engagement with the shoulder 12 on the jaws, and the jaws into stronger clamping engagement This engagement can be made very secure by the application of a wrench to the nut 4t,

There are, of course, modificationswhich may be made inth'e disclosure made herein which will fall within the scope of my in vention as I have attempted to disclose only my preferred form.

I claim: j

1. A conductor supporting device comprising in combination a pair of pivoted clamping jaws, a support for the jaws comprising a boss member having means for attachment to a hanger and an elongated pintle member projecting from opposite sides of the support parallel to the conductor, supporting means on the jaws to engage the pintle member and allow the aws to pivot thereon and gripping means to clamp the conductor, a clamping member to engage the jaws and move them into engagement with the conductor and having H prising .in combination a pair of pivotal clamping jaws, a support for the jaws compris'i'nga boss member having means for attachment to a hanger and a pintle member projecting longitudinallyof the conductor I from the support, supporting means on the jaws to engage the pintle member and allow attachment to a hanger and a pintle mem ber projecting in diametrically opposite directions and parallel to the conductor, supporting-means on the jaws to engage-the pintle member and allow the jaws to pivot thereon and gripping means to clamp the conductor, a clamping member to engage the jaws and move them into engagement with the conductor and having means through which the pintle and boss may be passed and means having a threaded engagement with the supporting member tomove'the means into engagement with the clamping member to move the'clamping member into engagement with the jaws.
